To allwkom it may concern." i

.Be it known thatl, JOHN H. RIGBY, a citizen of the United States, residing at Beverly, in the county of Essex andState ofMa ssachusetts, have invented certain Improvements in Heel-Building Machines, of

Whichthe, following description, in connectionIwith the accompanying drawing fiS a specificatlon, l ke reference. characters on the drawings indicating like parts inthe several figures.

f -This inventionrelatestoheel building ma- 1' (chines, and is of special utility when embodied in that type ofmachine inwhich heel lifts are assembledin a mold for nailing and there held by a' presser mounted to swing into position for operation by a member acf 'tuatedby power through the medium. preferablyof a power shaftprovided with a Horton clutch,includingthensual roller cage and tripping arm, such a machine ,forming the subject of Letters Patent No. 1,148,716 granted Aug. 3, 1915. Certain features oi the invention, however, are not l1m1ted their utility to use in connection with a ma chinelof thefparticular kind'referred to, but may bejembodied in many difi'erent machines for operating upon shoes. f

. An important object of this invention is to obviate the possibility, with a machine of this, character, ofpermitting"the-presser to be actuated by the power-actuated member,

with resulting disasterto the machine, when the presser occupies a rearward pos tion, not w in proper alinement with the mold. l i,

1 Such a contingency may arise, because the Horton clutch is tripped; by swinging the presse'r arm" forward, and if this "be done j whenthe power is turned off, as may occur 4H) for example, possible,with the form of starting mechanism f herfetofore n "use, to

by accident or design during the lunchhour,

swingbaclr the presser'arm without throwingofi' the'clutch, and. accordingly, when the power is turned fon, the presser is'automati- "cally actuated by the clutch, and notfbeing 'over"t he mold, the presser engages other i parts ofthe machine destructively.

In accordance with this invention, therei rea er the heel mold 18.

fore,means are provided for preventing the power devices, in such machine, from jact latinsthe presserf nemb r Wh n t hasfbee w nnnncuninine Madman complished by providing connective means,

such as a link, pivotally mounted on the swinging presser-operating member, and

, constructed and arranged to be engaged with the roller cage of the Horton clutch, acting i upon the latter to rotate itlbackward and throw off. the clutch whenever the gpresseroperating member is swung back from normal presslng poslt on cal embodiment of the invention will be specifically described for the purpose of illustration, butit should be understood that theinvention is not limited: in its scope to The various vfeatures of my invention will i be illustrated in-the accompanying drawing and described fullyin-the specification and teriorconstruction. i 4 i In ts general features the machine illustrated embodiesfwith some differences in design), the devices forming the subject of .ithe aforesaid patent, to which reference may be had for a more detailed explanation.

. The frame of the machine is designated bythe reference numeral and may be of any suitable shape and. construction. Pivotally mounted within the frame 10 .is-a

swingin farm 12 whichis constructed to sw ng a out the pivot pin 1 L mounted on a lever 15 whichf is. depressed, after the starting of the machine, by a cam 132 upon the main drive shaft 128, thus applying pressure .to the heel presser .72, provided that the latterhas been swung forward fromthe position illustrated, in which position, however,'my invention provides that powercan not bdapplied to depress arm 12. and presser 72, which would destroy the parts at the Theoperation oi cam 132, by shaft Specification of IettersPatent.
